For RS -10 Reservoir Sensors: • Pipe fitting connections provide quick, easy access to sensor and reservoir without disconnecting any electrical or piping connections. • Sensor includes riser pipe cap with a length of flexible conduit which is connected to a NEMA 4 or NEMA 6 electrical junction box (contractor supplied). • PVC riser pipe cap slips on and off the PVC fitting installed on top of riser pipe.

Fiberglas Reservoir Installation Detail for Extreme High Water Conditions Concrete Traffic pad Reservoir Vent to Grade Plug Factory Drilled Holes FRP Reservoir Double -Wall Tank Optional RM Reservoir Monitor: • Optional sensor requires no electrical power source. • Sensor includes riser pipe cap with electronics and battery pack. • Riser pipe cap slips on and off PVC fitting which is installed on top of contractor supplied riser pipe. • The internal, replaceable power source is a battery with a 5 -year estimated life. This should be tested periodically. 16 • To test, simply push button on top of cap. Light shows green for liquid in reservoir, red for no liquid in annulus. No light indicates loss of battery power. C6. Electrical AWARNING • Do not place intrinsically safe sensor wiring in the same conduit as non -intrinsically safe wiring. DO • Make certain all electrical work conforms to local codes. • Wire reservoir sensor to the control panel using wiring specified on control panel wiring diagram. CAUTION: Place wiring in water tight conduit and junction boxes (to maintain leak detection capability). C7. Testing To simulate low liquid level condition: • Remove sensor from Fiberglas reservoir. To activate low level alarm: • Remove sensor from fluid in reservoir. To activate high level alarm: • Fully immerse sensor into a bucket of water. C8. Reservoir Leak Detection What to do for an alarm condition: • Remove the riser cap. • Extract reservoir sensor. • Use dipstick to measure reservoir liquid level: ❑ If dipstick measurement is 1.25" (2" for tanks 15,000 gallon capacity or larger) or less, reservoir has drained, indicating a low level alarm. ❑ If dipstick measurement is 14" or higher, the high level alarm has been activated. For a Low Level Alarm: • Refill the reservoir to 1/2 full. • Continue monitoring. For a High Level Alarm: • Remove liquid from reservoir until it is 1/2 full. • Continue monitoring. If alarm occurs and reservoir level is normal: • Consult your local electrician. ❑ Control panel is improperly wired or has a defective component. • See section D9 on Control Panel False Alarms. Important: If an additional low level or high level alarm occurs, call Owens-Corning Field Service Office nearest to you. See phone numbers on page 2.
